The Face

The market for self-monitoring of blood glucose (SMBG) approached $8.8 billion worldwide in 2008. Yet despite dramatic double-digit growth in sales of SMBG products since 1980, the business is now facing declining prices and slower dollar growth. Given that SMBG meters and test strips are viewed by consumers and insurers as essentially generic products, it will be extremely challenging for new market entrants to displace well-entrenched existing competitors without a truly innovative technology. Also, in the face of declining glucose test strip prices, market expansion can only occur through identification of more of the undiagnosed diabetes population and convincing existing diabetes patients to adopt glucose testing or to test more frequently. Ultimately, a combination of technology innovations, patient education, and economic incentives may be needed to significantly expand the SMBG market and build sustainable long-term dollar growth for SMBG vendors.

Au Nanodots

Au nanodots decorated Cu2O nanooctahedrons were fabricated by a facile liquid-phase process combined with a galvanic replacement reaction for nonenzyme glucose detection. A simple rapid test strip based on the nanooctahedrons was proposed to evaluate the possibility of commercial application in nonenzymatic glucose detection. This test strip shows excellent response toward glucose. Linear response was obtained over a concentration ranging from 0.05 mM to 15 mM, and the detection accuracy is 0.05 mM. The good detection performance in selectivity, stability, and feasibility proving the great potential application in human blood glucose monitoring. This study demonstrated the possibility of a high-performance nonenzyme glucose test strip based on metal-oxide nanostructures decorated by catalysts.

Diabetes and its complications have become a worldwide concern that influences human health negatively and even leads to death. The real-time and convenient glucose detection in biofluids is urgently needed. Traditional glucose testing is detecting glucose in blood and is invasive, which cannot be continuous and results in discomfort for the users. Consequently, wearable glucose sensors toward continuous point-of-care glucose testing in biofluids have attracted great attention, and the trend of glucose testing is from invasive to non-invasive. In this review, the wearable point-of-care glucose sensors for the detection of different biofluids including blood, sweat, saliva, tears, and interstitial fluid are discussed, and the future trend of development is prospected.

BACKGROUND The prevalence of gestational diabetes mellitus (GDM) is increasing in Singapore and the cost of providing traditional care for GDM is high. Mobile health (mHealth) applications may act as useful tools in the management of GDM. OBJECTIVE The objective of this mixed-methods study was to measure the usage behaviour and explore users’ perceived usefulness of the Habits-GDM application when managing GDM in a randomised controlled trial. METHODS We conducted a quantitative analysis of the application usage behaviour in 170 Habits-GDM application users and 14 semi-structured interviews with users from a randomised controlled trial. RESULTS The convenience of automatic data transfer of weight values to the Habits-GDM application helped users (116/170, 68%) log their weight at least once a week. However, when the application had usability challenges, users avoided using that feature, i.e. users logged only an average of less than one meal/week out of the recommended six meals/week. Of the usability challenges, many users (12/14, 85.7%) mentioned food items not worded in the commonly known way and limited ethnic food database as the primary barriers. Only half of the users (84/170, 49.4%) accessed the educational lessons, but many (9/14, 64%) identified the provision of always available, valuable health-related information as an advantage of the educational lessons. ‘Healthy eating’ and ‘Why exercise’ were the most (56/84, 66.67%) and least (38/84, 45.24%) frequently accessed educational lessons, respectively. Users (10/14, 71.4%) reported sending messages to the coach via the chat interface only when they faced logistic issues and 86.45% of all the coach messages were replies typed by the research coordinator in response to the logistics issues (i.e. a request for blood glucose testing strips and appointment confirmation) raised by the users. Healthcare professionals lack of access to the coach’s dashboard discouraged users from asking queries related to GDM via the e-coaching feature. CONCLUSIONS The findings suggest that mHealth application acts as a useful tool in managing GDM. Culturally sensitive mHealth applications with a provision for women to interact with healthcare professionals should be developed in cooperation with the users. CLINICALTRIAL Not applicable.

Abstract Background In March 2017, Togo was declared the first country in sub-Saharan Africa to eliminate lymphatic filariasis as a public health problem, but post-validation surveillance has been lacking. In some areas of the country, migrant groups from neighboring countries that are still endemic for LF pose a risk of reintroduction of LF to Togo. The objective of this study was to identify the risk posed by migrant groups by measuring their prevalence of LF infection and investigating any positive case using Togo’s case investigation algorithm to prevent resurgence of LF and sustain Togo’s elimination success. Method A cross-sectional study was conducted in 2018 in the northernmost region of the country. Three migrant populations were identified: (i) nomadic Peuhls, (ii) Togolese members of local communities who migrate annually to neighboring countries for seasonal labor, and (iii) refugees from Ghana who came to Togo because of a communal conflict in Ghana. A questionnaire was designed to collect data on demographics and history of LF and MDA; all participants were tested for circulating filariasis antigen (CFA) using the filariasis test strip (FTS). Any CFA-positive case was confirmed with nocturnal microfilaremia. Results Refugees, seasonal economic migrants and nomadic Peuhls represented 42.1%, 31.4% and 26.5% of the study participants, respectively. The overall prevalence of CFA was 4.2% (58/1391) with the highest prevalence in the nomadic Peuhl group (11.9%), but only one of them (0.07%) was confirmed positive with nocturnal microfilaremia. Using the case investigation algorithm, no other positive case was identified in the positive case’s surroundings. Conclusion This study demonstrates that nomadic Peuhls, with a CFA prevalence of 11.9%, pose a potential risk for reintroduction of LF into Togo while Ghanaian refugees and seasonal economic migrants do not appear to pose a significant risk. Periodic monitoring of migrants, especially the nomadic Peuhl population, is a potential post-validation surveillance approach that could be used to promptly detect any LF cluster that may arise.
